Abstract:

The optimization of a multifrequency eddy current test was performed for the detection and characterization of second-number corrosion using computer programs. The results of the analytical studies showed that both inner and outer surface corrosion could be detected and quantified. Air gap variations could also be distinguished from corrosion using multifrequency data. These results were confirmed experimentally using phase-sensitive eddy current instrumentation. Author
